Yes. Why would you imagine an explosion not causing a shock wave? Are you thinking of 'super-sonic' shock waves?

If an explosive causes a supersonic shockwave, it is called a 'high explosive'. If the shockwave is slower than local sound, it generates a wave more like a solition, though I am unclear the difference between a solition and a sub-sonic shock wave.

it says: "...A shock wave ....is a type of propagating disturbance. Like an ordinary wave, it carries energy and can propagate through a medium (solid, liquid, gas or plasma) or in some cases in the absence of a material medium, through a field such as the electromagnetic field.

Shock waves are characterized by an abrupt, nearly discontinuous change in the characteristics of the medium.[1] Across a shock there is always an extremely rapid rise in pressure, temperature and density of the flow..."

These two statements, for example, appear inconsistent.

Can we get a shock wave in outer space...in a vacuum...sure, see the latter part of the article......how does that fit (or not) in these descriptions??
